GRAND RAPIDS -- A 25-year-old Grand Rapids man who openly carried a holstered handgun into Aberdeen Elementary while voting Tuesday did so legally, but used 'extremely poor judgment," Kent County Prosecutor William Forsyth said in a ruling.

He said the law does not prohibit someone with a properly registered gun, as well as a concealed-pistol permit, to carry an openly visible weapon into a school. The person may not, however, carry the weapon into a school if it is hidden or concealed.

"Did he really believe that by carrying a gun into an elementary school that no one would notice and that no one would react?" he wrote.

"In conclusion, I can only hope that Mr. Looman heeds the advice of the Grand Rapids Police Officers who responded to this incident; 'just because you have the right to do something doesn’t mean you should do it.'"

He noted that Looman chose to bring the weapon into the school "in the immediate aftermath of a fatal school shooting in Ohio."

In his ruling, Forsyth suggested that conflicting state laws, and exceptions to laws, allow for the unusual circumstance that happened Tuesday.

He aid the state's "weapons free school zone" law does not apply to someone with a concealed weapons permit, but at the same time that person may not carry a hidden weapon into a school. That person may carry a non-concealed weapon into the school, however.

"While I do not know whether the legislature intended this result when it enacted these statutes, it is nonetheless the consequence of its actions," Forsyth wrote.
